欠けると同時に、製作コストが高くなる。In US Pat. No. 4,156,354, torque is provided through roller bodies that are circumferentially equidistantly spaced in the joint assembly and are disposed between inner and outer joint members. A high speed, high torque transmission coupling is shown. Each roller body is received in a flat recess in the inner joint member to allow radial sliding relative to the inner joint member. This construction is complicated, the dimensions of the joint are large, and it requires very good surface finish and low manufacturing tolerances. For these reasons, and the increased friction resulting from the sliding relationship of the flat surfaces, this type of joint lacks smoothness of operation and is expensive to manufacture.

No. 2,910,845 discloses a constant velocity universal joint for connecting two rotating members which is not a joint having an angularly staggered joint but axially aligned or slightly offset. The fitting is shown. Therefore, this type of constant velocity universal joint has limited utility. Further, this type of coupling uses a spherical drive member that is constrained to rotate about a journal provided in the drive member. Restraining the drive member increases friction, which is not desirable for a universal joint.

A socket 29 is provided at one end of the outer joint member 26 to receive the illustrated ratchet wrench 27, or other device to be driven. An enlarged portion 38 that is enlarged is provided adjacent to the socket 29. The expansion part 3
8 is provided with three straight grooves 39 which are circumferentially separated. The grooves 39 may be equally spaced around the circumference and their shape is right cylindrical with respect to the plane transverse to the outer joint member 26. In the single type constant velocity universal joint, the enlarged portion 38 of the outer joint member 26 is the inner joint member 25.

して起こることを理解すべきである。Also, when the inner joint member 25 is fully bent into an articulation, it must be deformed to hold all the roller balls 40 in the straight groove 39. The deformed portion prevents free movement in the axial direction and does not hinder the rotation of the shaft even when it is bent up to 30 degrees from the outer joint member. It can be seen that with this structure, the spherical roller ball 40 makes spherical contact, and all the torque is transmitted to the straight groove 39 via the roller ball 40. An embodiment of the invention using four roller balls can be made, as shown in FIG. This embodiment can be used to transfer large torques. As before, a plurality of (four in this case) straight grooves 39 are provided at equal intervals around the enlarged portion 38 of the outer joint member 26. The openings 41 of the inner joint member 25 must meet the same requirements as before, and these four openings 4
1 are provided at right angles to each other. In this case, because the cross section of the inner joint member is reduced, some material is left in the center of the inner joint member to reinforce it, as indicated by reference numeral 25a, and The spherical contact between the two roller balls 40 is still maintained. It should be understood that the transmission of torque in those joints is primarily due to the interaction of the roller balls 40 in the spherical straight grooves 39.

A standard ball detent is provided in the form of a ball bearing 50 held by. Next, referring to FIG. In this figure, another embodiment of the single type constant velocity universal joint is shown. In this embodiment, the socket 29 is not shown for ease of illustration. As before, the outer joint member 26 is provided with an enlarged portion 38. In the enlarged part,
A plurality of spaced straight grooves 39 are provided in which a plurality of roller balls 40 are received. Similar to the embodiment shown in FIGS. 7 and 8, the cross section of the groove 39 is preferably cylindrical. The roller ball 40 is received in the opening of the head 42 of the inner joint member 25. When the inner joint member is articulated with respect to the axis away from the outer joint member axis, the roller ball 40 is pulled out of the straight groove 39 so that the torque transmission plane is no longer relative to the outer joint member axis. You can see that it is not vertical. I mean,
This is because the roller ball 40 of the present invention performs rotation and linear motion without restriction. This is a feature that conventional constant velocity universal joints do not have.

継手より大幅に進歩する。As shown in FIG. 12, when the constant velocity universal joint is stationary, one roller ball 40 is sufficiently pulled out from the groove 39, but the remaining roller balls 40 are gravitationally moved to the groove 39. Held in. However, when the joint starts to rotate as shown in FIG. 13, due to the circumferential force, all the roller balls 40 will move to the inner joint member 2
Immediately equidistant from the axis of rotation of 5, and slightly out of the straight groove 39. As you can see from the figure,
In this situation, the torque transmitting points will make point-to-point contact at approximately the same location between the roller ball 40 and each straight groove 39. In the present invention, the moment arm from the center of rotation to the point T is shorter than the moment arm of any conventional universal joint, thereby transmitting torque more efficiently and smoothly. This feature, combined with the unconstrained rotation of the ball as the joint rotates, results in less frictional forces, which makes the joint of the present invention a significant advance over conventional joints.
